420 grade stainless steels have high tensile strength after heat treatment. Under normal conditions, this material has an average corrosion resistance. 420 quality is in the group of martensitic stainless steels. Its workability is very good in its annealed state, and the shavings of the 420 quality material in the annealed state are easily broken and do not swarf. This quality stainless material can reach very high surface hardness after heat treatment.
420 grade stainless steel is often used in the machinery industry, petroleum and petrochemical industries, food and food manufacturing plants, decorations, transportation, shafts, pistons and valves.
